Disp fx of nk of 3rd MC bone, r hand, subs for fx w malunion

This code signifies a right-hand injury involving a displaced fracture of the neck of the third metacarpal bone. It specifically indicates that the patient is in a subsequent phase of care for this fracture, and malunion (imperfect healing) has occurred.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed displaced fracture of the right third metacarpal neck, and the physician documents malunion. This applies when the fracture is no longer acute but still requires management due to the healing complication.

• Ensure documentation clearly specifies "displaced fracture" and "neck of third metacarpal" on the right hand.
• Confirm the encounter is for follow-up care and that "malunion" is explicitly stated by the provider.
• Do not use for initial encounters or for fractures healing normally.
